@nietras1 @EgorBo Yeah I have kinda the same opinion, unless there happens to be some roslyn fixer which automatically applies the lowest valid combination of unsafe, I kinda doubt I will use that much.

@EgorBo To me this seems way to verbose for existing unsafe code and have a hard time seeing me adopting this in any existing code. Aka I don't want to litter code with unsafe blocks and yet another indent level... I'm guessing this is not seen as a concern?

TL;DR on the upcoming changes in C# vNext for 'unsafe' (blog post devblogs.microsoft.com/dotnet/improvi…)

@KooKiz Old enochian trying to summon a demon?

Claude is doing great today

@lucasmeijer @xoofx Yup, I went straight to roslyn analyzers for a lot of weird code GPT 5.4/5.5 produces. static mutables, lock() in quite a few places, abstract base classes with all the Code instead of one concrete type etc.

@xoofx i'd say go straight to analyzer for that kind of stuff, instead of praying model behaves.

I'm so annoyed by GPT-5.5 adding static mutable data (e.g. via `ConcurrentDictionary`) that I'm starting to think that I should add a rule to the system prompt itself. 😒

@xoofx Funny, I'd expected that Copilot would have used the most tokens, as MS has complex guardrail system prompts

Another evaluation of different providers (Copilot, Codex, OpenAI) with the same model GPT-5.5 High, really interesting to see the differences. 🤔

@SitnikAdam Yay for ProcessStartInfo.KillOnParentExit, no more manual job object pinvoke

@davidfowl Or only if you look at it. Maybe it's Schrödinger Slop.

It's only slop if you don't look at it 😅

@jhalbrecht @shanselman Sir, you have a high tolerance for pain.

@shanselman I've got a diesel Jeta with a 5 speed : - ) and I use vim

@migueldeicaza Flore, if you want Michelin starred dutch inspired cuisine.

Friends, I am in Amsterdam next week. Please send food recommendations - what’s the absolute meal I shouldn’t miss?

I've built a full LLM inference engine in C#/.NET 10. From scratch. Not a wrapper - native GGUF loading, BPE tokenizer, attention, KV-cache, SIMD-vectorized CPU kernels, CUDA GPU backend, OpenAI-compatible API. Solo dev, ~2 months, AI-assisted (not vibe-coded!). First preview is out. Check it out for mode details at kokosa.dev/blog/2026/dotl… and dotllm.dev

Can someone explain this to me in programming terms?

@ErikEJ Your Benchmark table is weird, async with 1.7s, sync with 33ms and below your writing about async with 0.06s. I think it's missing a row

Just blogged: Get a 180% speed increase on large async reads with Microsoft .Data.SqlClient (and EF Core) - here is how to turn it on! #dotnet #efcore #sqlserver #performance erikej.github.io/sqlclient/dotn…

@EgorBo You should change your stackalloc Code example 512 int32 ist larger than 1024 Bytes, the safe value declared above

AI is unlikely to cure cancer. I think we might make significant scientific and medical progress in the near future, but it is important to understand the state we are in. We are in a decade-long scientific stagnation. Outside of computing, progress is historically slow. We struggle to find who should receive a Nobel prize in Chemistry or Physics. Some will tell you that we have simply exploited all the low-hanging fruits. Somehow, just as the 1970s arrived, we reached the apogee of scientific progress. I have another much more credible explanation. Let us examine stagnations in general. During the 2010s, we lamented the stagnation in microprocessors. Our CPUs ran hot, and they were no longer much faster. "We reached the end, processors won't get much better from now now". It turns out that the dominant player (Intel) was the one stagnating. This was unthinkable. Intel had the best engineers, the best technology in the world. Surely, if you could do much better, someone would have done it by now? Turns out that Apple, AMD and others eventually did. It just took time. What about Alzheimer's? One researcher, Sylvain Lesné, published a paper entitled "A specific amyloid-β protein assembly in the brain impairs memory". The paper had made up images although it took some time before everyone learned about the fraud. Meanwhile, somehow, everyone in the world accepted that Alzheimer's was cased by amyloid-β proteins. Every other avenue was closed. It is only after we invested billions to dollars to create drugs capable of eliminating these proteins, and more money yet to engage in clinical trials, that doubts emerged: it does not work. Why doesn't it work? See the pattern? There is one unified culture with everyone thinking along the same lines. Thomas Kuhn described science as having “normal science,” which is largely incremental and sterile, and “revolutionary science,” where new ideas emerge and paradigms are challenged. He wrote about this in The Structure of Scientific Revolutions (1962). If you want to cure cancer or Alzheimer's, you need revolutionary science, not the other kind. So how do you get revolutionary science? You cannot buy it. We multiplied the number of researchers in the last century, and we have little to show for it. So why did we start getting less and less revolution science in everything but computing starting in the 1970s? The decline in revolutionary science outside computing since the 1970s stems from increased government bureaucracy and government funding models, resembling Soviet-style five-year plans. It is when "peer review" became the norm. It is when credentialism and technocracy took charge. While not all science is sterile, much is constrained by this cultural shift. Changing it is tough but possible—revolutionary breakthroughs often come from a few determined scientists and engineers, not masses. To get out of this stagnation, we need to spread a better culture. It would be useful to kill the 'linear model of innovation' (that all progress originates from university professors thinking hard in their offices). We need to greatly diminish the role of peer review. We need to greatly diminish the role of PhD programs: stop the focus on credentialism. It is should flat out embarassing to ask a scientist to write a 5-year plan.

@monkeyonahill @gregyoung Language Sensitive Editor en.m.wikipedia.org/wiki/Language-… The reference manuals for RSTS/E are orange binders en.wikipedia.org/wiki/RSTS/E

@gregyoung C'était du BASIC stylé, non ? Non.

I was posting a comment to an article and it led me to wonder ... How many developers have used LSE? hint/clarification: you likely had orange books if you did.

@ibrahimsuta @DamianEdwards computerbase.de/artikel/prozes… in german, but Google translate should work fine

@DamianEdwards Do you have any benchmarks on this? I am also curious how much of a difference it makes compared to e.g 9950x.

Oh man how I'd love to build a full-fat Threadripper 9980X system just to see how quick it can build the dotnet repos. 128 threads, dual PCIe Gen5 drives, up to 2TB of quad-channel DDR5 6300. Anybody at AMD want to send me a reviewers kit? 😁

@RogerAlsing Gonna call Sarah Connor

Once AI makes manual coding obsolete, What will you work with instead? Any ideas? Coding is my only skill tbh :-P

@dodyg Closed everything. I like the enum stuff, not sure about closed as another modifier, but not having to do the ArgumentOutOfRange Exception dance would be nice

The C# team is considering "closed enums, closed hierarchies, case classes, and nominal union types." github.com/dotnet/csharpl…

@EgorBo @ben_a_adams @neuecc It appears to be that the typeof(T) == typeof(byte), Unsafe.As code and similar code by now generates the same asm. #v2: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" target="_blank" rel="nofollow noopener">sharplab.io/#v2:EYLgxg9gTg…

@torn_hoof @ben_a_adams @neuecc I would be surprised if it is on any runtime

I've blogged about ZLinq, my new OSS for C# and Unity. It is a Zero-Allocation LINQ Library for .NET and covers all .NET 10 LINQ methods. neuecc.medium.com/zlinq-a-zero-a…

@EgorBo @ben_a_adams @neuecc Likely slower, at least that's what I remember. Not sure with recent jit improvements though

@ben_a_adams @neuecc Well, I meant in general, but speaking of that particular part, can it be just like this?
